return

[1]

[2]

[1, 2]

[2]

[1]

[2, 1]

[1, 2, 3]

[4, 5, 6]

Problem

Given two arrays numbers1 and numbers2 consisting of natural numbers, write a function solution that returns the result of combining numbers1 and numbers2.

Constraints

Each element in numbers1 and numbers2 is a natural number not exceeding 20.
numbers1 and numbers2 are not empty, and each has a length not exceeding 10.

Test Case

Test Case Number	numbers1	numbers2	return
1	[1]	[2]	[1, 2]
2	[2]	[1]	[2, 1]
3	[1, 2, 3]	[4, 5, 6]	[1, 2, 3, 4, 5, 6]

Explanation for Test Case 1

Combining numbers1 = [1] and numbers2 = [2] results in [1, 2].

Explanation for Test Case 2

Combining numbers1 = [2] and numbers2 = [1] results in [2, 1].

Explanation for Test Case 3

Combining numbers1 = [1, 2, 3] and numbers2 = [4, 5, 6] results in [1, 2, 3, 4, 5, 6].
